Got files - so you want two of the cam socket ones and one of each of the others?

All looks fine to me to get moving,

Brian,

(edited 3 times to make it sound right, god damn)


Yes 2 of the 3 bolt cover, 1 each of the 4 bolt covers.

The plan is the gasket side gets faced

The outside the rib and bolt bosses get faces but the boss raised boss on the 3 bolt cover is not faced....so it they look like the ferrari covers

the overall thickness is not very important....I think it's drawn 5mm to match the ferrari parts but +/- 2mm would be fine I'd say as long as they are all similar.

After having reverse engineered many ferrari parts I've found that they utilized offset holes at about every chance and randomly. Also a weird pattern of 76mm spacing for studs, holes etc.. on multi-hole parts. I think at this point I have an entire v8 engine in SW.

looking good.

Ok so as mentioned these all got pulled into cad/cam. To save on a lot of machining and finishing, these are going to be machined in a few basic operations. If I were to ''3d mill'' then my pencil finishing stepovers would have to be sanded smooth. The less time I spend sanding the better, as Ive done my fair share of sanding and polishing moulds.

Unless you see it first hand, its UNBELIEVEABLE how tiny blemishes on the pattern can print to sand, and thus onto part so these patterns will get painted as you would a car once machined.

They will be cut from Brazilian Mahogany since they are thin. I could use some high density foam but I only stock 100mm board and its $$$$.

Ive a day left to do on the cnc still - revamped the console and enclosure a bit and also added a larger 1.5hp pump for flood coolant and it all got a bit more involved than I had intended as I said I may as well do it right.

The good news is the cam is done + draft + shrink, and I also got the machining and jigging figured out so thats good.

It should all be pretty swift once It starts.

Ill throw up a few surface finish samples tomorrow and you can take your pick Mark!
